Dielectric relaxation

A diagrammatic representation of polar molecules in an electric field. When the field is applied
the molecules orientate themselves so that the end of the molecule with a small positive charge faces the negatively charged electrode. When the field is removed, the molecules slowly relax to their previous state.

This is a movie that shows diagrammatically how simple polar molecules in a fluid phase might respond to an electric field. In real instances each molecule would also have substantial translational velocities.

You can apply a field by clicking on the switch symbol. More information is available about the molecule when you move your mouse over the top left hand instance.
